Abstract
This work deals with a description of a digital television broadcasting in the DVB-T, DVB-C, DVB-S and DVB-H. It also deals with a brief description of a single frequency SFN network as well as with a reception of DVB signal. The next section describes the simulation of software RadioLab 3.5.0, simulation of models of the DVB-T signal coverage in the Ostrava region for particular transmission points and their graphical representation on the map. Intensity values of electromagnetic field gained by the simulation model are obtained in the third part. They are practically verified by measuring in the predicted measurement points.
